[Embodiment of the invention]

 Hereinafter, various embodiments of the cap of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing a cap 20 according to a first embodiment of the present invention together with a part of a container body 1, 1 is a PET container body, 2 is an opening, and an outer peripheral surface of the opening 2. Although not shown in the figure, a male spiral portion 3 is formed. These are the same as the conventional ones shown in FIGS. The cap 20 according to the first embodiment has a longitudinal unevenness 22 formed on the outer peripheral surface of the cap body 21 and a radius as one of the opening and closing force reducing means integrally formed with the cap body 21 at one location on the peripheral surface. A projection 23 is provided to project in the direction. The protruding portion 23 is formed at a position above the connecting portion 9 described with reference to FIG. The structure other than the above of the cap 20 may be the same as that shown in FIG. 11, for example, and the description thereof will be omitted. This point is the same in the following embodiments, and a description thereof will not be given.

According to such a cap 20, the cap 20 can be rotated by hooking the thumb, the index finger, the middle finger, or the like on the protruding portion 23, so that the radius of the action point for rotating the cap 20 is reduced. As a result, the rotation force acting on the cap 20 by the principle of leverage can be increased as compared with the conventional cap including only the cap body 21. In other words, the cap 20 can be rotated with a smaller force than before. Therefore, not only can the cap 20 be easily opened, but also the cap 20 can be easily and reliably closed, and leakage or deterioration of contents can be prevented.

Further, by forming the projecting portion 23 as the opening / closing force reducing means integrally with the cap body 21, the opening / closing force reducing means manufactured separately from the cap body 21 is bonded or screwed to the cap body 21. As compared with the case of mounting by, for example, manufacturing is easier and cost can be reduced.

The projecting portion 23 projects horizontally from the outer peripheral surface of the cap body 21, and the outer dimension D 1 of the projecting portion 23 is smaller than the outer dimension D 0 of the container body 1. Since the overall height does not increase, there is no need to increase the size of the packaging container due to the presence of the protrusion 23. Therefore, the transportation cost does not increase.

FIG. 2 is a perspective view of the cap 30 according to the second embodiment of the present invention. The cap 30 has longitudinal irregularities 32 formed on the outer peripheral surface of the cap main body 31, and is provided at a plurality of positions (four in the illustrated example) on the outer peripheral surface at regular intervals in the circumferential direction and symmetrically. A protrusion 33 is provided integrally with the cap main body 31 and serves as an opening / closing force reducing means.

According to the cap 30 as described above, the cap 30 can be rotated by hooking other fingers such as a thumb and an index finger or a middle finger on the plurality of protrusions 32, and thus the cap 30 can be rotated. A larger force can be applied than in the case of the cap 20 having the protruding portion 23 at only one position, that is, the cap 30 can be easily and reliably opened and closed with a smaller force.

The outer dimension D2 of the protrusion 33 is larger than the outer dimension D1 of the protrusion 23 of the cap 20 in FIG. 1, but is larger than the outer dimension D0 of the container body 1 (see FIG. 1). Since it can be stored small and the overall height dimension does not increase, the presence of the protrusion 33 does not require the packaging container to be increased in size and does not increase the transportation cost.

FIG. 3 is a perspective view of the cap 40 according to the third embodiment of the present invention. The cap 40 is formed by forming irregularities 42 on the outer peripheral surface of the cap body 41 and integrally forming, for example, a butterfly-shaped projection 43 on the top of the cap body 41 as opening / closing force reducing means. . According to such a cap 40, the cap 40 can be rotated by sandwiching the butterfly-shaped protruding portion 43 between the thumb, the index finger, the middle finger, and the like. Therefore, as in the first and second embodiments described above, The cap 40 can be opened and closed with a small force.

Instead of the butterfly-shaped protrusion 43, a protrusion such as a semicircle or a square, or a bar-shaped protrusion extending in the horizontal direction may be formed. In addition, by forming the shape of the protrusion 43 into a shape such as a flower or an animal, a design effect can be obtained.

FIG. 4 is a perspective view showing a state in which the opening / closing force reducing means of the cap 50 according to the fourth embodiment of the present invention is opened. The cap 50 is formed by forming irregularities 52 on the outer peripheral surface of the cap body 51 and integrally forming a projection 53 as an opening / closing force reducing means that can be freely opened and closed on the top of the cap body 51. In such a cap 50, a shielding plate portion is provided below the protruding portion 53, and the contents leak or deteriorate due to an opening formed when the protruding portion 53 is opened. Don't do it.

The projecting portion 53 is normally closed, and is opened and projected as shown in the figure when the cap 50 is opened and closed, so that the projecting portion 53 is formed together with the irregularities 52 on the outer peripheral surface of the cap body 51. The cap 50 can be rotated with a finger, and the cap 50 can be opened and closed with a smaller force than before. In addition, by always closing the protruding portion 53, it is possible to prevent the height dimension from becoming large, so that the size of the packaging container can be reduced. Can be reduced in size, and transportation costs can be reduced.

FIG. 5 is a perspective view of a cap 60 according to a fifth embodiment of the present invention. The cap 60 has an unevenness 62 formed on the outer peripheral surface of the cap body 61, and a projection 63 such as a dome is integrally formed on the top of the cap body 61. As an example of a locking portion capable of locking the opening / closing auxiliary means, a through hole 64 having a circular cross section is provided.

According to such a cap 60, the opening and closing assisting means 65 such as a round bar-shaped chopstick is inserted and locked in the through hole 64 of the projecting portion 63, and the opening and closing assisting means 65 is rotated. A remarkably larger rotating force can be applied to the cap 60 than the caps 20, 30, 40, and 50 of the first, second, third, and fourth embodiments. Further, the size and height of the projecting portion 63 can be reduced, and the amount of material used for the projecting portion 63 can be reduced by the through hole 64 serving as the locking portion, so that the material cost can be reduced. .

The through hole 64 can be used for other than the opening and closing operation of the cap 60. For example, in the summer season, the cap 60 is closed in the container body 1 containing juice, wine, and the like, and the container body 1 is immersed in ice water through a through-hole 64 through a rubber string or the like, and the elasticity of the rubber is reduced. The use of force to rotate and invert the container body 1 allows the contents such as juice and wine to be cooled more quickly, that is, in a shorter time than simply immersing the container body 1 in ice water. Can be.

FIG. 6 is a perspective view of a cap 70 according to a sixth embodiment of the present invention. The cap 70 has an unevenness 72 formed on the outer peripheral surface of the cap body 71, and a projection 73 formed on the top of the cap body 71. The projection 73 has another opening / closing assisting means such as a square bar. As an example of a locking portion that can lock the groove, a square groove-shaped concave portion 74 is formed.

According to such a cap 70, the opening and closing assisting means 75 such as a square bar is inserted and locked in the concave portion 74 and the opening and closing assisting means 75 is rotated, so that the first opening and closing assisting means 75 are attached to the cap 70. -It is possible to exert a remarkably larger rotating force than the caps 20 to 50 of the fourth embodiment. In addition, since the height of the projection 73 can be reduced as compared with the projection 63 having the through hole 64 shown in FIG. 5, not only the material cost can be reduced, but also the size of the packaging container can be reduced, and The cost of containers can be reduced, the size of packages during transportation can be reduced, and transportation costs can be reduced. In addition, since the concave portion 74 serving as the locking portion is formed in the shape of a square groove, the opening and closing assisting means 75 inserted into the concave portion 74 is less likely to come off from the concave portion 74 during the rotation operation than in the case of the arc groove-shaped concave portion. There is.

FIG. 7 is a perspective view showing a cap 80 according to a seventh embodiment of the present invention. The cap 80 is formed by forming irregularities 82 on the outer peripheral surface of the cap body 81 and forming, for example, a flat hexagonal column-shaped projection 83 on the top of the cap body 81 as opening / closing force reducing means. It is.

According to such a cap 80, the projection 85 formed on the top of the cap main body 81 is provided with the hole 85 of the wrench 84, which is an opening / closing auxiliary means, having a hole 85 conforming to the shape of the projection 83. By fitting and rotating the wrench 84, a large rotating power can be obtained. The height of the protrusion 83 can be significantly smaller than that of the protrusions 43, 63, 73 of the caps 40, 60, 70 of the third, fifth, and sixth embodiments. It is possible to reduce the cost of materials, reduce the size of packaging containers, and reduce transportation costs.
